What is payload?

Payload is the weight of the revenue cargo a vehicle carries — gross vehicle weight minus tare (empty) weight. Maximizing legal payload is the goal of load planning.

Payload is the weight of the cargo a vehicle actually carries — the revenue-earning portion of the load. It is the difference between the loaded weight and the empty weight:

Payload = gross vehicle weight − tare weight

Maximizing legal payload

With the federal gross limit fixed at 80,000 lb, the way to carry more payload is to reduce tare weight (lighter equipment) and to distribute the load so no single axle group caps you before the gross limit does. A load that hits an axle limit at 76,000 lb gross is leaving 4,000 lb of legal payload on the table — which is exactly what balancing the center of gravity recovers.

What is tare weight?Tare weight is the empty weight of a vehicle or container with no cargo. Payload plus tare weight equals gross vehicle weight.What is gross vehicle weight (GVW)?Gross vehicle weight (GVW) is the total actual weight of a fully loaded vehicle — tractor, trailer, fuel, driver and cargo. The federal Interstate limit is 80,000 lb.What is axle weight?Axle weight is the portion of a vehicle's total weight carried by a single axle or axle group — the number weigh stations and the Bridge Formula regulate.
